The emergency escape breathing apparatus consists of 12 components

1. Mask: It is a large field of view window, the window lens is made of polycarbonate material, which has high transparency, strong wear resistance, anti-fog function, mesh hood wearing mode, comfortable and convenient to wear, and the colloid is made of silicone, which is non-toxic, tasteless, non-irritating, and has good airtightness.
2. Gas cylinder: It is an aluminum liner carbon fiber fully wound composite cylinder, with a working pressure of 30MPa, with light weight, high strength and good safety performance, and the cylinder valve has a high-pressure safety protection device.
3. Bottle belt group: The bottle belt card is a fast cam locking mechanism, and ensures that the bottle belt is always in a closed-loop state. The cylinders do not flip over.
4. Shoulder straps: made of flame-retardant polyester fabric, the strap adopts a double-sided adjustable structure, so that the weight falls on the waist and hips, reduces the pressure of the shoulder strap on the chest, and makes breathing smooth. And there is a wide elastic padding on the shoulder strap to reduce the pressure on the shoulder.
5. Alarm whistle: placed on the chest, the alarm sound is easy to distinguish, small in size and light in weight.
6. Pressure gauge: large dial, with night vision function, equipped with rubber protective cover.
7. Gas cylinder valve: with high-pressure safety device, small opening torque.
8. Pressure reducer: small size, large flow rate, stable output pressure.
9. Back support: The back support is designed in line with the principle of ergonomics, injection molded by carbon fiber composite materials, with flame retardant and anti-static functions, light and strong, and lined with elastic pads on the inside of the back support, which can make the wearer comfortable.
10. Belt group: buckle locking, easy to adjust.
11. Quick connector: small, one-handed operation, with locking and anti-disconnection function.
12. Supply valve: simple structure, strong functionality, large output flow, bypass output, small size.
In general, an emergency escape breathing apparatus is composed of compressed air cylinders, pressure reducers, pressure gauges, air delivery tubes, hoods, backpacks, etc., which can provide a constant flow of gas for more than 10 or 15 minutes. It can be used for people in toxic, harmful, smoke, and oxygen-deficient environments.
